ABSTRACT:
In a recording apparatus to record data by applying a light beam of high and low intensities onto a recording medium (disk), the intensities of the reflected light beams from the disk for the two kinds of light beams are detected to control the light intensity for recording in synchronization with the timing of the bits formed on the disk. In a recording apparatus which records data supplied from a data source via a buffer memory, data is recorded on the disk in a specified recording density by controlling the recording operation in accordance to the occupation ratio in the buffer memory.
